AutoREALM provides several ways to measure distances. The main units of distance for the map control the physical scale of the map. You can make measurements using any available unit by right-clicking, choosing Change Unit, and selecting the unit you want.

Ø Measurement String

-
After selecting this ruler, draw along the map to determine the distance of a non-linear route.

Ø Pushpins
-
To measure the distance between the cursor and up to four other points, stick a push pin in the map by right-clicking, choosing Place Pushpin, and selecting a color. The pushpin toolbar will show the distance and angle between the cursor and all the active pushpins.
-
Ø Grid
-
Finally, the obvious (and crudest) method is the Grid method. Just count the number of squares in a straight line between two points and multiply by the number of units you've set per square.
